Annotation: The article provides a technical solution for building a switching unit. Its conflict-free nature, fault tolerance, and compactness are investigated. Using the example of a 16-pin switching unit, it is shown that the proposed structure allows performing electrical connections with 100% use of external pins. Two options for implementing 8 circuits on a 16-pin switching unit are given. The fault tolerance is shown. The proposed approach to building a switching unit allows to implement a switching unit of any size with a reduced number of switch elements.
